Someone gave me a swimming, underwater Finis Neptune MP3 player but the problem is the charging cable was not included. Since this is a waterproof MP3 player the cable is proprietary and it is impossible to find a cable (from the company or otherwise) without buying a second unit on eBay with the cable.

My 1st question: Is there a way to cut apart an old USB cable and make my own charger/transfer cable?

My 2nd question: There are four contacts on the bottom of the MP3 player. How do I map each one to know what is positive, negative, ground and data transfer? (Photo of pins attached)

 Thanks!

I can't answer the 2 questions but this company states it's in stock but I question it because they say it ships in 1 to 2 months. You may want to contact the company. Good Luck.

Edit: I did a little research and the cable has the following UPC

~~I did a search and this Ebay site with an sg domain (Singapore) has it. The seller is in the U.S. You should be able to contact him with any questions~~.

Sorry, the seller has ended the listing.
